The heating device as illustrated in the drawings consists of a pair, ofheating elements 10, which are arranged in opposed relationship. Whilethese elements may beshaped in various ways to accommodate the device todifferent types of waving apparatus with which it may be employed, forthe particular type of waving apparatus which I shall subsequentlydescribe, the elements are preferably relatively fiat and rectangular incontour. -Each element is formed with a metal sheath formed of suitablematerial, such as sheet aluminum, with an internal electrical resistanceelement.

As illustrated in Figs. 3,' 4 and 5 the metal sheathof each elementisformed by a piece of sheet metal 11' having its edge portions bentlaterally by a suitable press operation. A suitable flat resistanceelement 12 is accommodated within sheet metal piece 11, and the sheathis then completed by another piece of sheet metal 13. Crimped edges 14serve to overlap the edges of the sheet metal piece 13; to lock the twoparts of the sheath together. Extending along the ends of each of theheating elements 11, there are tongues 16, formed integral with thesheath. Likewise for a purpose which will be presently made clear, thelower longitudinal edge of each element 10 is preferably formed toaiiord longitudinal lips 17, which extend inwardly toward each other. I

The mounting means for the heating elements 10 includes a pair ofmembers 21, which are preferably formed of a suitable molded insulatingmaterial which will not readily conduct heat, as for example a moldedphenolic condensate product containing a certain amount of asbestosfiber as a filler. Each of the members 21 includes a lower portion 23 ofsufiicient dimensions to entirely encompass the outer surfaces of theelements 10, and an upper portion 24 of reduced width serving as afinger hold portion to facilitate manipulation by an operator.

Relative movement between members 21 is afforded by a suitable hingeconnection. Thus integral tabs 26 and 27 are shown extending from theinner face of the members 21, and these tabs are connected by a pivotpin 28. A suitable spring 29 associated with pivot pins 28, serves tonormally bias or urge the lower portions 23 together. Members 21 aresubstantially duplicates with exceptionof the spacing of lugs 26 and 27,for connection with the pivot pins 28.

As illustrated more clearly in Fig. 7, the inner face of each of themembers 21 is formed to afford air pockets 31, which are segregated bythe web 32. Web 32 extends downwardly from an integral boss or pad 33,which is provided with apertures 34.

The vertical end edge portions 36 (Figs. 4 and of members 21, areprovided with parallel grooves 37, adapted to slidably receive thetongues 16 of the heating elements 11. When the tongues of the heatingelements are fitted within grooves 37, it will be noted that one face ofthe sheath of each element, may contact the adjacent faces of web 32 andboss 33. Likewise with the elements in proper assembled relationshipwith respect to members 21, it will be noted that the upper and lowerends of pockets 31 are open to the atmosphere, to permit passage ofupwardly flowing convection currents of air.

In order to permit making of electrical connections to the heatingelements, a pair of electrical connectors or terminal posts 39 aremounted upon the outer faces of each of the members 21 and 22. Theseterminals 39 are connected to lead wires 41, which extend thru theaperture 34. Suitable refractory bushings or tubes 42 surround the leadwires 41 (Fig. 4) and the inner ends of these bushings likewise fitwithin apertures 43 provided in the sheet metal piece 13 of the adjacentheating element. This interlock serves to retain the elements 11 inproper operating position. Terminals 39 are also shown connected toconductors 44, of a flexible electrical cord 46. .These conductors leadthru apertures 47, in order to extend between the fingerhold portions24. In order to hide the terminals 39, together with lead wires 41, theapertures 34, and the adjacent portions of conductors 44, I providesuitable cover plates 49 (Fig.3), which can likewise be made of suitableinsulating material, such as a phenolic condensate product, and whichcan be secured to the outer faces of members 21 and 22, by means ofscrews 51.

Before describing the mode of operation of my device, it will benecessary to briefly describe the type of apparatus illustrated in Figs.8 to 11 inclusive, with which the device is particularly adapted tooperate. This apparatus includes a protector 52, adapted to be used inconjunction with a plurality of curlers 53, 54 and 55. Protector 52includes the two bar-like structures 56 and 57 which are hingedlyconnected together by pivot pin 58, and which may be clamped togetherupon a strand of hair, by locking means including link 59 and cam lever61. One end of bar 57 is provided with an upstanding post 62, formedchannel shaped and of sheet metal. A similar post 63 is mounted uponlink 59. A

pointed element 64 is mounted upon bar 57, to part or divide the strandof hair gripped by the protector. When the protector is in closedposition upon a strand of hair, the posts 62 and 63 are adapted toreceive the curlers 53, 54 and 55, one upon top of the other. Curlers 53and 54 can be substantially duplicates, having enlarged ends adapted toloosely fit within posts 62 and 63.

Curler 55 is shown provided with an end stud 66, adapted to be receivedwithin a slot 67 formed in post 62. This stud is also provided with asquared head 63 to receive a wrench. The other end of curler 55 is boredto receive a pin 69. Pin 69 is provided with a spring clutching element71, such as are well known in the art, whereby pin 69 can turn only inone direction with respect to the body of curler 55. The squared head 72of pin 69 is adapted to be received within a slot 73, formed in post 63.

Apparatus such as is described above is described generally and claimedin said copending application of Ralph M. Keele, Ser. No. 612,950. Itmay be explained briefly that in using this apparatus the hair strand isdistributed on all of the curlers or waving forms, and that when thewrap upon all of the curlers has been completed, the curlers occupy aposition as shown in Fig. 11. A flannel pad 76, moistened with asuitable wavin solution, is then placed over the wound hair, and myheating device is then applied over the pad. In applying the heatingdevice the heating elements 10 are separated by forcing the fing-erholdportions 24 together, and then the fingerhold portions are released topermit the spring 29 to force the heating element 10 against oppositesides of the wound hair. It will be noted that lips 17 engage upon theunder side of the lower curler 53, thus tending to retain the heatingdevice in proper position. It will also be noted that the upper edges ofthe heating elements 10 terminate short of the axis of the upper curler55. This is for the reason that curler 55 and the hair wound upon thesame tend to be heated toa greater degree than the other curlers, due tothe natural rise of heat. Therefore it is not only unnecessary to extendthe heating elements to a greater height, but by proportioning theseelements as shown, undue heating of the upper curler and the portion ofthe strand wound upon the same, is prevented.

It has been found that members 21 will not deteriorate when elements 10are heated to a degree such as is required in permanent waving. Iattribute this to the fact that ample ventilation is afforded by thepockets 31, and because a minimum area of direct contact is affordedbetween the heating elements 10 and the molded insulating material.Tongues 16 have a fairly loose engagement with grooves 37, and to thiseX- tent the heating elements may be said to be floating within members21. After the device has been in use for some time the surface layers ofinsulating material in direct contact with the heating elements becomeslightly charred, but this charring does not continue to a detrimentaldegree, and actually appears to afford greater heat insulation.

While I have described my device as being operated from a supply ofelectrical current, and while certain features of my invention relateparticularly to such. electrical devices, it is possible to substitutesuitable heat storage elements made of suitable material, such as solidaluminum, in place of electrical heating elements 10. In this event theheat storage elements must of course be far preheated to a determineddegree, before applying th same to the wound hair.

I claim:
